T0 all whom t may concern: A

Be it' known that 1,PEDERBRIX, a citizen of the United States,r`esiding at Omaha, in `the county of Douglas and State of Nev brasl-a, have invented new. and yuseful Improvements. 4in Handle-Grip Control for Motor-Cycles, of which the following is a specification.

lThis invention relates to improvements in y motor-cycles, and more particularly to a handle grip controlfor motorcycles.

The object of this inventionis to vprovide a motorcycle with a handle `gripcontrol by A which the rider mayl control the spark throttle, muliler and clutch without moving his hands from the handle-bars.

tion are illustrated upon the accompanying sheets of drawings, yet it is' to be understood that minor detail changes Vmay be made without departing from the scope thereof.

AFigure l isa view in perspectiveL illus-y trating the application of this invention.v vFig. 2 isa central, longitudinal sectional view through the' handle grip.` Fig. 3 isa plan view with the. outer casing ory handj grip removed. Fig.` .tis -a transverse `sectional view taken onthe lines 4 4 of Fig'. 2.

F ig. '5 is a plan rview with the operatingv .sleeves removed and oneflockingsleeve retionof the operating ring 19iY -V y In order that the rider of afmotorcycle 1n ay'have complete control without removing hisjhands from the handle bars,y each hand grip is detachably connected with twocontrol rods or wiresmo'unted within the handle barswith their free ends passingtheremoved. Fig. G is a partialview yin end elevathrough and connected by suitable means to the spark control, throttle, mutller control,

and engine clutch, respectively.

As the operation of both hand grips are the same, it will be necessary to describe but` one. As illustrated on Fig. 2, a guide block l is secured within the end of the handle bar 2 and is provided with twolongitudinal guide ways of unequal length `ifor receiving the ends of two control rods 3 and t. The handle har is slotted longitudinally adja cent the termination of each guide-way and to the ends of control rods are attached operating blocks 5 adapted Vto travel withiny the adjacent slots. Two independent operating sleeves G and 7 are mounted on the handle bar, having helical grooves 8 engaging thel operating blocks 5 of the respective controly Specification of Letters Patent.

forward control rod is reciprocated. By sliding the hand grip rearwardly the other control rod may be reciprocated.

In order to lock the operating sleeve while not operatively connected to the hand grip,

the outer end of each sleeve is provided with` aplurality of teeth 20. A locking sleeve 21 is placed between each toothed end and the passed and secured to the handle bar 2,

thereby allowing only a longitudinal movement of the sleeve.

Each locking sleeve is normally held in engagement with the adjacent operating sleeve by means of a spring 25. The length of the sleeve is such that when the hand grip is moved forward the internal shoulder 11 will engage the ange 22 on the forward locking sleeve and withdraw it from engagement with the forward operating sleeve 6, and the spring 25 acting upon the rear locking sleeve 21 will retain it in engagement with the rear operating sleeve 7 and lock the same against rotation while it is disengaged. from the hand grip.

What I claim is:

l. A handle-grip control for motorcycles, comprising a hand grip on each handlebar, two control rods mounted in each arm of the handle bar and extending within thev hand grips, operating blocks upon the ends of each control rod adapted to slide in longiv tudinal slots provided in the arms of the handle bar, rotatable sleeves mounted upon the handle bar about each slot having helical grooves adapted to receive ythe ends of the operating blocks, and means for connecting and disconnecting the respective sleeves to the hand grips.

2. A handle-grip control for motorcycles, comprising a hand-grip, two control rods mounted in the handle bar and extending within the hand grip, a block upon the end of each control rod adapted to slide in a longitudinal slot provided in the handle bar, a rotatable sleeve mounted upon the handle bar about each slot having a helical groove adapted to receive the end of the operating block, means for connecting and disconnecting the respective sleeves to the hand grip, and means to lock the disconnected sleeve.

3. A handle-grip control for motorcycles, comprising a hand grip mounted to slide longitudinally upon the end of the handle bar,

two control rods mounted in the handle bar and extending within the hand grip, a block upon the end of each control rod adapted to slide in a longitudinal slot provided in the handle bar, a sleeve rotatably mounted lupon the handle bar about each slot having a helical groove adapted to receive the end of Vthe operating block, the adjacent ends .of the sleeves provided with a plurality of longitudinal grooves, and an operating ring secured upon the inner side of the hand grip having teeth adapted to engage and be entirely received within the slots upon one sleeve to rotate the sleeve so engaged.

4. A handle-grip control for motorcycles, comprising a hand grip mounted to slide longitudinally upon the end of the handle bar, two control rods mounted in the handle bar and extending within the hand grip, a block upon the end of each control rod adapted to slide in a longitudinal slot provided in the handle bar, a sleeve rotatably mounted upon the handle bar about` each slot having a helical groove adapted to receive the end of the operating block, the adjacent ends of the sleeves provided with a plurality of longitudinal grooves, an operating ring secured upon the inner side of the hand grip having teeth adapted to engage and be entirely received within the slots upon one sleeve to rotate the sleeve so engaged, and means to lock the disconnected sleeve.

5. A handle-grip control for motorcycles, comprising a hand-grip mounted rotatably upon the end of each-handle bar and having a limited longitudinal movement thereon, means for limiting the longitudinal movement, two operating rods mounted to reciprocate within each arm of the handle bar and extending within the respective grips, two spaced-apart operating sleeves rotatably mounted upon theV handle bar within each hand grip, a connection between each sleeve and one operating rod adapted to reciprocate the operating rod upon rotation of the sleeve, the outer end ofleach sleeve provided with a plurality of teeth, a locking sleeve at each other end having a limited longitudinal movement and `provided with teeth adapted to interlock with the teeth on the adjacent sleeve, means normally causing the teeth to engage and lock, means upon each locking sleeve adapted to be engaged by means upon each hand grip when moved in one direction to release that locking sleeve from the adjacent operating sleeve` and means upon each hand grip to engage and operate the freed locking sleeve. n
